How do configure my power dashboard correctly with a FRITZ!DECT 200 to show a correct price?

hi there,

i would be very happy if someone could tell me, how do I configure this correctly so see a correct price.
because I tried with last option (a fixed price) and saw a price-calculation on my energy dashboard
and kwh that is totally wrong.

these are the existing entities this sensor has:

when it comes to “showing/calculating costs” i see a price of >60€ for 1,54 kWh which
is obviously wrong :wink:

thanks for any help !!!
